Determine first if you need RAW at all. RAW is used to squeeze out all the available data for maximum quality, for example when you are printing big. However, 95% of today's users are only showing their photos on a screen. In that case JPEG is sufficient because a screen and JPEG have about the same dynamic range. And actually the dynamic range of the JPEG is only reproduced on a very good monitor and with reduced lighting in the environment.
So, be aware what you want to accomplish, otherwise you are wasting your time, and you feel a robot after some time when you need to convert every single RAW photo to JPEG by applying the same settings, and struggling to get the same quality and appearance of a JPEG produced with one of the Custom Image settings.
My impression is that many users shoot RAW because they think it looks professional, but they actually don't need it. Take a look on Ricoh's web site on the Photographer’s Perspective page, quite a few (professional) photographers are shooting JPEG with Custom Image.
